According to WebMD, functional ovarian cysts do not endanger pregnancy, so it is possible for women with them to have babies. Some ovarian cysts resolve on their own, while others require treatment before they go away. It is important for women to have regular pelvic exams so a doctor can diagnose the severity of any cysts or other growths on the ovaries before pregnancy
Functional cysts commonly develop during treatment with clomephine-based drugs, which are used to combat infertility. According to WebMD, these cysts typically go away several months after treatment is completed and do not have any adverse effects on pregnancy.
WebMD states that a functional ovarian cyst is caused by slight changes in the way the ovaries release or produce eggs. Functional cysts can develop during a regular monthly menstrual period. A simple or follicular cyst occurs when the small follicle or egg sac on the ovary does not release an egg. This leads to swelling with fluid either on the surface of the ovary or inside of it. A luteal or corpus luteum cyst is the most common type of ovarian cyst. This occurs when the remains of the egg follicle do not dissolve and continue to fill with fluid.
